2つ目の指標である「標準化の性質と程度」は，もっと込み入っている．この指標には2つの側面があり，第1のものは "the degree of difference between the standard form or forms of a language and all other varieties of it" (24) である．つまり，言語変種間の差異性・類似性の度合いに関する側面である（関連して「#1523. Abstand language と Ausbau language」 ([2013-06-28-1]) や「#1522. autonomy と heteronomy」 ([2013-06-27-1]) を参照されたい）．
第2の側面は "the nature of the standardization and the degree to which a standard form is accepted as such throughout the community" (24) である．Ferguson (24--25) は3段階を設定した．

・ St0. --- "a language in which there is no important amount of standardization" (ex. Kurdish) (24)
・ St1. --- a language which "requires considerable sub-classification to be of any use. Whatever scheme of classification is developed, it will have to take account in the first instance of whether the standardization is unimodal or bi- or multimodal, and in the case of more than one norm, the nature of the norms must be treated" (ex. bimodal Armenian, Greek, Serbo-Croatian, Norwegian; multimodal Hindi-Urdu) (25)
・ St2. --- "a language which has a single, widely-accepted norm which is felt to be appropriate with only minor modifications or variations for all purposes for which the language is used" (24)
